When you visit the set of AMC's hit show "The Walking Dead," you can't talk about anything you saw. Everything from the blood on a walker to which of the cast is actually still hanging around is a potential, internet-melting spoiler.

So when MTV News headed down to Atlanta to sneak a peek at the AMC show's upcoming season five, we were pleasantly surprised at how open the cast was about what's coming up on the show.

"The new season has been nothing short of amazing," Steven Yeun, who plays Glenn said when asked about the anticipation for season five. "Just the buzz has been really big in our group and our crew, and I'm just really excited for everyone to see it."

Okay, so maybe not the most ground-breaking news about the show — but certainly when the cast and crew are excited, that tends to boil over on screen, as well. Danai Gurira, who plays Michonne, agreed with that assessment.

"The new season is going to be really thrilling," Gurira said. "It's been really exciting, actually. You get really fascinating, character driven and action driven scripts. You bring them to life and learn even more layers of what's going on."

Got it. So season five has characters, action, and layers. That's a pretty big scoop. Maybe Sonequa Martin-Green (Sasha) could add something to this?

"The characters are asking, 'Who am I now?' Things have been taken from us. A lot of stuff has gone wrong," Martin-Green said. "'Who are we as a group, and who am I as a person in the aftermath?' That's a big theme that's being hashed out this season."

There we go, thanks Sonequa! We know that season five picks up with the zombie-apocalypse survivors trapped in a train car at the not-so-safe sanctuary of Terminus (and we actually know a little more than that, if you read our spoiler-free recap of the season premiere). And now we know at least emotionally where the group is headed in the rest of the season... Those who survive Terminus, of course.

Speaking of survival, sounds like things are going to get pretty dire, pretty quick.

"We're all used to the gore and the horror factor of the show," Christian Serratos (Rosita) said. "So it's saying something when even we get scared reading the scripts. How are we going to do that? Can we air that?"

"This is our best season so far," Norman Reedus, who plays fan favorite Daryl Dixon added. "I remember we were shooting the first episode, and I was leaning in to Andy [Lincoln], and going, 'Man, this stuff is never gonna make it to TV.' And he leaned over and he said, 'You say that every single year.' "

"It's the most ambitious season we've ever attempted," Lincoln said, "and certainly there are a couple of episodes that are probably my favorite that have ever been written."

You can check out the premiere for yourself when it airs on AMC on Sunday, October 12. And head back to MTV News throughout the weekend - and next week - for some in depth (and actually spoilery) talk with the cast.
